THOMAS J. CORNING, OF SAN J OSE, (UUJFORNIA.

BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 403,738, dated May 21, 1889.

Application filed. January 29, 1889. Serial No. 298,016. (No model.)

To all whom it may concern..-

Be it known that I, THOMAS J. CORNING, a citizen of the United States, residing at San J os, in the county of Santa Clara and State of California, have invented a certain new and useful Improvement in Baling- Presses, of which the following is a specification.

This invention consists of certain new and useful features of construction and combina tions of parts, hereinafter described, and pointed out in the claims.

This invention also involves mechanism for actuating the plunger and feeding the material to be baled into the press.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a longitudinal vertical partial section of the press through the dotted lines :r 00 of Fig. Fig. 2 is an enlarged detail view of the press shown in Fig. 1. Fig. 3 is a longitudinal horizontal partial section of the same through the dotted line 00 a," of Fig. 1. Fig. 4 is an end view of the press. Fig. 5 is a plan View of the central portion of the same. Fig. 6 is a horizontal section of the plunger through the dotted line a m of Fig. 2. Fig. 7 is a detail view of double cranks and shaft for driving the press-feeder. Fig. 8 is .a detail view of double cranks, shaft, dog, and arms for opera-ting a folder, to be described hereinafter.

Like letters of reference indicate corresponding parts throughout the several views.

A represents the main frame of the press, which is rectangular in form and consists, essentially, of the side pieces, A, cross-pieces A and posts a A all of which parts are firmly secured together. The frame A is provided with a floor, A whereon the plunger slides to form bales and along which the latter are driven to discharge them from the press. The upper side of the frame is partially inclosed by means of boards A. The central portion of the frame is provided with side boards B, to which are secured uprights B, through which horizontal rods B pass, the latter having thumb-nuts 13 applied to their ends, which are threaded. The end portion of the frame is also provided with side boards B to which are secured uprights 13', through which are passed horizontal rods 13", having thumb-nuts B applied to their ends, which are threaded.

The lateral diameter of the portions of the press included between the side boards, B B may be diminished, as indicated by dotted lines, by turning the thumb-nuts B.

For convenience in referring thereto the central portion of the press will be designated as the baling-chamber and the righthand end portion as the compression-chamber.

E is a gear-wheel mounted on the horizontal shaft 1, which is provided with bearings E E E are horizontal bearing-pins projecting from the opposite sides of the wheel E, one pair of said pins, as E, being located preferably twice the distance from the shaft E that the pins E are.

F represents guide-bars, the functions of which will be described hereinafter, connected with the press, preferably by means of upright portions F.

G is a reciprocating plunger, which is in form a quadrangular box minus one end.

G is a hinge-plate provided with lugs G and attached to the inside of the end of the plunger.

G3 is a longitudinal slot in the lower portion of the plunger G. v

II is a bifurcated pitman jointed by one end thereof to the lugs G of the hinge-plate G.

The bifurcation H of the pitman H adapts the latter to slide nearly its entire length provided with notches 1-1 H 011 the under side thereof to adapt the sameto engage with the bearing-pins E E", whereby power is transmitted from the gear-wheel E through the pitman to the plunger.

H represents guide-pins projecting transversely from the outside of the free end of the pitman suiiiciently to allow the same to engage with the guidebars F, whereon they are adapted to slide, and whereby the pitman is disengaged from the pins E E after each operative stroke of the plunger.

I represents helical springs-a preferable formattached to the plunger G in any suitable manner, and provided at their free ends with eyes I.

I represents connecting-rods having one pair of their ends jointed to the eyes I of the spring I and their other ends passed through openings in the upright portions F of the astride the gear-wheel E. The pitman H is.

guide-bars F, wherein they freely slide, as indicated by dotted lines, and wherefrom they are prevented from escaping by means of nuts 1 J is a horizontal rock-shaft having double cranks J rigidly connected with the ends thereof.

J 2 is a dog, also rigidly attached, preferably, to the central portion of the same. The shaft J passes through the bottom of the balingchamber of the press.

J 3 is a folder mounted by means of the arms J 4 upon the top of the press, whereto they are attached by means of hinge-joints J J are connecting-rods connecting the folder J through the arms J 4 with the free ends of the double cranks J, whereby said folder is operated.

J T are forks attached to the back side of the folder J and their office will be more fully described hereinafter.

K is a shaft having double cranks K rigidly connected therewith.

K are axes projecting transversely outward from the free ends of the cranks K, whereto they are also rigidly connected. The axes K are mounted horizontally inthe posts a, between which the cranks K are revoluble.

L is a longitudinally-reciprocating feeder provided with downwardly-curved teeth L, projecting from the under side thereof, for conveying material to be baled into the spout of the press. The upper end of the feeder L is mounted upon the shaft K, whereon it revolves when in operation. The lower end' of the feeder L is supported and guided by means of pintles L projecting from the edges thereof into the grooved ways L in the side pieces, L The lower end of the feeder L is provided with longitudinal slots L to admit the passage of the forks J 7 therethrough, for a purpose to be described hereinafter. The parts L L L serve to form a spout, L for conveying material from the hopper L into the baling-chamber of the press.

M is a gear-wheel meshing with the gearwheel E, mounted on the horizontal shaft M, which is provided with bearings M M is a sprocketwheel mounted 011 the shaftM. M is a driving-pulley, also mounted on the same shaft.

K is a sprocket-wheel mounted on the outer end of one of the axes K K is a chain belt connecting the sprocket- .wheels M K and serves to transmit power from the sprocket-wheel M to the shaft K,

which drives the feeder L.

To operate the press I proceed as follows: Supposing the plunger and pitman to be in the positions indicated by the dotted lines y in Fig. 2, the press to be charged in the usual way, and the hopper L to be filled with hay,

apply power to the pulley M which being transmitted to the feeder L, the latter will convey the hay downward into the spout L whence it is forced into the baling-chamber by means of the folder J and the forks J Simultaneously with the operations above described the bearing-pins E engage with the notches 1-1 in the pitman H, which, together with the plunger G, will be driven to the positions indicated by the dotted lines y. When the pitman and plunger reach the points last indicated and the bearing-pins E disengage from the notches H and simultaneously with such disengagement the bearing-pins E engage with the notches H in the pitman H, the latter will drive the plunger G to the position shown in full lines in Fig. 2. When the plunger and pitman have reached the position shown in full lines in Fig. 2, one charge of the material to form the bale will have been driven into the compression-chamber of the press. Immediately thereafter the bearing-pins E passing downward, become disengaged from the notches H and the plunger G and the pitman II are driven by the action of the springs I and the elasticity of the material being baled to the positions indicated by the dotted lines y. A repetition of the simultaneous operations just described will add another charge to the bale. Obviously any number of charges within the limit of the press may be united to form the bale. The folder J with its forks J are raised to the position shown in Fig. 1 by means of the bottom of the plunger passing over and pressing downward the dog J which operates the shaft J, cranks J, and rods J Upon the return of the plunger to the position indicated by the dotted, lines y, the dog J is released and enters the slot G in the plunger G, and the folder J with its forks, descends of its own weight, carrying with it the charge of hay just accumulated in the spout L I wish to call particular attention to the manner in. which power and motion are transmitted from the bearing-pins E E to the pitman and plunger. By locating the bearingpins E near the periphery of the wheel E, I obtain increased speed for the first two-thirds of the stroke of the plunger, while the material is loose in the press. Afterward the bearing-pins E, being located near the shaft of the wheel E, transmit less motion and double power, as the material becomes more compact, to the finishing of the stroke of the plunger.

It will be found in practice that when the material being baled is dry it will be sufliciently elastic to force the plunger and pitman back to the positions indicated by the dotted lines y, little, if any, assistance being required from the springs I. When the aid of the springs is not required, I prefer to narrow the left-hand end of the baling-chamber the springs will be found to be indispensablewhen the material to be baled is wet.

When it is desired to increase the compactness of bales, diminish the lateral diameter of the compression-chamber throughout its entire length by means of the side boards and thumb-nuts B,

I claim 1. In a baling-press, in combination, the bifurcated pitman having notches therein and guide-pins thereon, the wheel provided with bearing-pinsone of said pins being located near the periphery of the wheel and the other nearer the shaft of the sameprojecting from the sides thereof and adapted to engage with the notches in said pitman, and guide-bars for supporting and guiding the free end of the pitman, substantially as described.
